--以dba身份连接sqlplus：
sqlplus sys/password@orcl as sysdba

--建立用户并使用默认的表空间：
create user wfw identified by wfw DEFAULT TABLESPACE users TEMPORARY TABLESPACE temp;

--授予角色：
grant connect to wfw;
grant resource to wfw;
grant dba to wfw;

--授权：
grant create session to wfw ;
grant create table to wfw ;
grant create any table to wfw ;
grant create any procedure to wfw ;
grant create any sequence to wfw ;
grant create any view to wfw ;
grant create any trigger to wfw ;

--创建表空间： --临时表空间： create temporary tablespace oaisdata_temp tempfile 'e:\develop\oracle11g\oaisdata_temp.dbf' size 50m autoextend on next 50m maxsize 20480m extent management local; --创建表空间 create tablespace oaisdata logging datafile 'e:\develop\oracle11g\oaisdata.dbf' size 50m autoextend on next 50m maxsize 20480m extent management local; --删除用户： drop user wfw cascade;
